I have occasional lines on my screen and give a blue screen error and reset the pc. I've experienced it in the R9 280. Is this problem chronic?
No this isn't something that AMD GPUs just do. If you have the same issue with 2 different video cards then you have other problems. Bad motherboard. Bad PSU. Dying OS drive. Defective cable. A bad cable can explain the lines. A piece of hardware dying can explain the crashing. You have included almost no information regarding you're PC so it's really hard to set you in the proper direction to troubleshoot.
